IMPROVEMENT IN EXPANDING HORSESHOES.

Specification forming part oi'Lettcrs Patent No. 110,][6 l, datedOctober 25, 1853.

To all whom, it may concern: Be it known that I, BENJAMIN PERRY SAEGENT, of Sutton, in the county of Merrimae, and State of New Hampshire,have invented a new and useful Improvement in Horseshoes; and I dohereby declare that the same is fully described and represented in thefell owing specification and the accompanying drawings, letters,Iigures, and references thereof.

OI the said drawings, Figure l denotes an under side view, and Fig. 2 anelevation of the rear end of my improved horseshoe.

My invention is intended eitherV to prevent or overcome the contractionof the frog or heel part of the hoof of a horse. This contraction takesplace from causes well known to farriers and others, and is oftenproductive of disease or lameness.

The nature of the principal part of Iny invention consists in making thequarters of the shoe separate from each other and uniting them together,or to a toe-bar by means of one or two joints,l and providing thequarters with one or Inore expanding screws, by which, when they aresecured to the foot of the animal, they may be expanded or moved apartfrom each other.

In the drawings, A and B denote the two parts of the shoe,` which Idenominate the quarter.77 They are united to the toe part C ofjoints,and turn, respectively, on joint-pins I) E. Y Each of the quarters A Bis provided with an ear or projection, as seen at e or f, which, whenthe shoe is applied to a horses foot, is made to turn upward into theconcave part of it and rest against the bar77 on the side of the frog.

In Fig. 3, -which denotes an under side view of the hoot of a horse, a aa exhibit the external surface ofthe sole of a concave form, b b, theinferior edge of the crust; c c, the junction of the bars with thecrust; d d, the points of the bars; e e, the bars, and f j' theconcavities between the bars and the frog.

The rear part of each of the quarters A B I is provided with a turningblock or calli, F

or G, which is so applied to the quarter by a journal, as seen in dottedlines at c d in Fig. 2,- as to be capable of being turned horizon`tally. A right-handed female screw is cut through one of the blocks,while a left-handed female screw is forced through the other. Twocorresponding screws, c Z), of a bar, H, are screwed into the saidfemale screws, so that when the bar is turned on its axis in onedirection the two quarters A B may be made to recede from 011e anotherand bear on their joint-pins D E.

By means of a shoe thus constructed the heel part of the hoof may beexpanded either after it has suffered contraction or while the same istaking place. By a judicious application of the expanding shoe andgiving to the screw H an occasional turn as the same may be needed acontracted foot may be either cured or greatly relieved.

The quarters A B are to be confined to the crust of the hooi' by nailspassed through the holes gg g, &c.

f Instead of forming the shoe in three parts, A B C, it Inay be made intwo parts jointed together; but this is not so good a plan, for it isnot desirable to have the strain of the expansion of the foot reacharound to the toe, as in such case it would be more liable to crack thecrust. By the employment of the ears e j" we transfer theexpansioirstrain from the confining-nails of the quarters to the saidears.

That I claim is- The combination of the bearers or ears e f with thejointed quarters or bars A B, jointed together or to a common toe pieceor calli, C, and operated by an -expansion screw or contrivance, asspecified.

In testimony whereof I have hereto set my signature this 24th day ofAugust, A. D. 1853.
